Abstract
The utility model discloses a novel cloth feeding mechanism for a sewing machine. The mechanism comprises a cloth feeding shaft and a crank. The cloth feeding shaft is a shaft body an outer surface of which is a smooth surface, a connecting portion and an adjusting portion of the crank are improved on the basis of a traditional technology, and the crank and the connecting portion are in an integrated structure; a cloth feeding shaft connecting hole is formed at a position where the crank is connected with the cloth feeding shaft, a clamping hole is opened on one side of the cloth feeding shaft connecting hole, and a locking screw hole for a shoulder screw to be screwed in is opened at the clamping hole; and the connecting portion and the adjusting portion of the crank are cast and molded accurately by one step, and the cloth feeding shaft is arranged at the cloth feeding shaft connecting hole and screwed through the shoulder screw, so that the cloth feeding shaft and the crank connecting angle is adjustable. According to the novel cloth feeding mechanism, due to structural and connecting characteristics of parts of the mechanism, the parallelism between the connecting portion on the crank and an axis of the cloth feeding shaft can be easily achieved during machining, the machining difficulty is low, most of materials are saved, the machining time is saved, and the part accuracy is guaranteed.
Description
Technical field
The utility model relates to a kind of stitch machine, especially relates to the cloth feeding mechanism in a kind of stitch machine.
Background technology
In the structure of Sewing machines, for guaranteeing the Sewing machines normal operation, cloth pushing shaft mechanism plays important effect, at present in the conventional art, cloth pushing shaft and crank design for integral structure, be arranged on connecting portion on the crank and be the screw structure and with the axial screw installation that offsets, the manufacturing technique that connecting portion and axial screw adopt is for carrying out roughing, fine finishining again after the heat treatment after forging; For the axial line that guarantees connecting portion and the axial line of cloth pushing shaft are parallel to each other, add and cause very big difficulty man-hour, and raw-material waste is very big, this connecting portion one end is that the thread other end is smooth shaft, for guaranteeing thread part and smooth shaft part coaxial inner conductor, fine finishining also causes very big difficulty after the heat treatment.The combination of processing back causes cumulative errors wayward.And top behind the screw is arranged when using, loosening phenomenon occurs, badly influence the synchronous problem of work feed.Therefore, practicality, economy on production efficiency and the working service have been restricted to a certain extent.
The utility model content
The purpose of this utility model is, at above-mentioned deficiency, provides that a kind of structural design is ingenious, compact, difficulty of processing is low, can guarantee the precision of parts, the novel sewing machine cloth feeding mechanism of having saved most of material again and having saved process time.
For achieving the above object, technical scheme provided by the utility model is: a kind of novel sewing machine cloth feeding mechanism, and it comprises cloth pushing shaft and crank, and described crank is provided with connecting portion, and this connecting portion and crank are integral structure; The position that connects cloth pushing shaft on the crank offers the cloth pushing shaft connecting hole, and cloth pushing shaft connecting hole one side offers the clamping opening, clamps and offers the locking screw that screws in for axial screw on the opening.
As a kind of improvement of the present utility model, the axial line of the axial line of described connecting portion and described cloth pushing shaft connecting hole is parallel to each other.
As a kind of improvement of the present utility model, described connecting portion is provided with smooth shaft, and this smooth shaft and crank are integral structure.
As a kind of improvement of the present utility model, described cloth pushing shaft is that an outer surface is the axis body of shiny surface, and this cloth pushing shaft one end is arranged on described cloth pushing shaft connecting hole.
The beneficial effects of the utility model are: the utility model has improved the structure on the crank conventional art, and the outer surface of cloth pushing shaft is the axis body of shiny surface, and the coupling part on the crank and crank are accurate one-shot forming casting system.The opening that the side of cloth pushing shaft connecting hole offers is tightened by axial screw, and the connection angle of cloth pushing shaft and crank can accurately be adjusted.Since the structure of this mechanism part be connected characteristics, add and be easy to realize that the axial line of connecting portion on the crank, cloth pushing shaft is parallel to each other man-hour, have the low advantage of difficulty of processing, namely saved most of material and saved process time again, and can guarantee the precision of parts.And terminal with compact integral structure of the present utility model, compactness, be easy to realize that cost is low, is beneficial to wide popularization and application.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, a kind of novel sewing machine cloth feeding mechanism that present embodiment provides, it comprises cloth pushing shaft 1 and crank 2, and described crank 2 is provided with connecting portion, and this connecting portion and crank 2 are integral structure; The position that connects cloth pushing shaft 1 on the crank 2 offers cloth pushing shaft connecting hole 21, and cloth pushing shaft connecting hole 21 1 sides offer the clamping opening, clamps and offers the locking screw 22 that screws in for axial screw 3 on the opening.
The axial line of the axial line of described connecting portion and described cloth pushing shaft connecting hole 21 is parallel to each other.
Described connecting portion is provided with smooth shaft 23, and this smooth shaft 23 is integral structure with crank 2.
Described cloth pushing shaft 1 is that an outer surface is the axis body of shiny surface, and these cloth pushing shaft 1 one ends are arranged on described cloth pushing shaft connecting hole 21.
In the present embodiment, cloth pushing shaft 1 is that an outer surface is the axis body of shiny surface, and difficulty of processing is low and save material and can guarantee machining accuracy; Crank 2, the coupling part and the adjusting portion that are arranged on the crank 2 are divided into accurate one-shot forming casting system.Add man-hour, cloth pushing shaft connecting hole 21 on the crank 2 is tightened lateral opening by axial screw 3 and is clamped cloth pushing shaft 1, and then the connecting portion on the processing crank 2, guarantee effectively when difficulty of processing is low that the axial line of connecting portion on the crank 2 and the axial line of cloth pushing shaft 1 are parallel to each other, saved most of material and saved process time.This axial screw 3 also is used for realizing adjusting the connection angle of cloth pushing shaft 1 and crank 2, and is easy to use.
As described in the utility model above-described embodiment, adopt structure same or similar with it and other cloth-feeding device of obtaining, all in the utility model protection domain.
